JACOB I'EELBEL, or NEW YoRK, N. it, ASSIGN'OR, BY MEsN ASSIGNMENTS, T0 UNION TYRE-WRITER COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom iii may concern u Be it known that I, JAooB Fannnn, a citizen of the United States, and resident of the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new 'to increase the rapidity with which tabulator work can be turned out. I do this by providing a tabulator key of such character that it can be operated by the palm or fiat part or bodyot' the hand without removing the fingers from the key-board, which thus requiresless attention on the part of the operator than has heretofore been necessary to actuate the tabulator. This key is an auxiliary key or additionalto the usual tabulat-or key and preferably it and its connections are in the nature of a simple attachment which can readily be put on any typewriter and can be removed or omitted as desired.

My invention consists in certain features of construction and combinations and arrangements of parts which will be fully set forth herein and particularly pointed out in the claims.

Tn the accompanying drawings, Figure 1 is a side elevation of a typewriting machine having my invention applied thereto, parts of the machine being shown in "ertical section. Fig. 2 is a fragmentary top plan View with part of the machine frame in section. Fig. 3 is a rear elevation of part-of the tabulator. Fig. 4 is a transverse vertical section showing the manner of securing the attachment to the frame of the typewriter. Figs.

5 and 6 are respectivelya top plan view, partly in section, and a side elevation, illustrating a modification of the invention.

I have shown my invention as an attachment to the Monarch typewriter. The main frame of said typewriter comprises a base 1 having a'forward extension that 'incloses the keyboard, said extension including a side bar 2. The posts 3, top plate 4, standards 5,

stationary rails 6, carriage 7, feed rack 8, feed pinion 9 and escapement 10 are all 0 the ordinary Monarch. construction, said TYPE-WRITING MACHINE.-

feed rack being as usual capable of'being lifted out of mesh with the pinion 9 in or 'der to releasethe carriage for a free run under the impulse of the spring drum 7..

The tabulator is also of a well-known construction and comprises a column stop bar 11 mounted 011 arms 12 projecting from the carriage 7 and having column stops 13 adjustably mounted thereon. These column stops are adapted to be engaged by an eagle-claw stop 14 which is pivoted at 1.5 to a bracket 16 secured to the upper stationary rail. 6 about the middle of the machine. This eagle-claw or stationary stop is normally held, by a spring 17 in the position shown in Fig. 1 whereit is out of the path of the column stops 13. The stop 14 is adapted to be movedinto the path of the stops 13 by'means of a push bar 18 projecting upward from a rack lifter 19, the

stem of which is operated in the usual way by a lever 20 pivoted to the underside of the top plate 4. Said lever is operated by a vertical pull link 21 connected at its lower end-,

tion of the rod 23 and is held by a check nut 23 in adjusted position. The rack lifter 19 has ears that lie beneath the feed rack 8 and the construction is such that when the key 24 is pushed towardthe rear of the machine, said rack lifter and the push bar 18 are moved upward, lifting the rack out of engagement with the pinion and moving the stop 14 into the path of the stops 13.

My attachment comprises a frame, clamp or supporting plate 25 which is mounted on the main frame of the machine in such a way that it can be secured to the typewriter without any modification of said frame. In mounting my attachment on the particular machine shown in the drawing, this plate, is secured to the right-hand side bar 2 of the forward extension of the. typewriter frame.- The support or bracket 25 consists of a plate of metal stamped out in the form shown and having at its upper part an ear or projection 26 which is bent around to cation of which in the present instance has conform to the curvature of the upper edge of the bar 2 and hook thereupon. Thebase 1 of the Monarch machine has an outwardly curved part 27 which constitutes a .sort of downward continuation of the post 3 and affords 'a socket for a rubber foot piece 27?.

The plate is curved as shown to extend around and back of this part 27 of the frame. At its rear-end said plate is secured to the base by a screw 28, the particular loeled form of the head of the screw, draws the plate 25 downward and the ear or book- 26 down into clamping engagement with the upper. edge of the bar 2.

this plate can be secured to the framework of'the machine in a very short tirneby means so simple .as torequire no especial skill. I

A' substantially horizontally disposed main lever 30 is pivoted at its rear end to the plate 25 at 31.- The lever 30 is'here' shown as made ofsheet metal and its'for ward end is bent or fashioned into a key 32 of a size considerably greater than that of ordinary finger keys. This key 32 lies over the frame bar 2 and has secured to its underside a buffer or cushion 33, of rubber or other suitable material,'-adapted to strike against the bar 2 when the key is fully depressed. A sub-lever 34; here shown as abell crank, is'pivoted to the plate 25 at 35 and the upper press against the key 24. The lever 34 has a rearwardly extendin arm 36 which is connected with the key l ever 30 by a link 37 pivoted to said key lever and -to the bell crank. The construction is such that when the key 32 is depressed the upper end of the bell crank 34 pushes the key 24 toward the rear of the machine and operates the tabulator. The bell crank 34 and key lever 30 may be restored to normal position by the restoring spring 17 of the tabulator.

In Figs. 5 and 6 I have shown a modification. In the form shown in the first four figures'of the drawings, the auxiliary tabu-' lator key is depressible, and I prefer that it be so. In Figs. 5 and 6 I have, however, shown an upstandin auxiliary tabulator actuating key adapted to be struck with the outer edge of the right hand and moved laterally. In said figures the plate 42 constitute a support corresponding to the plate 25 ofthe other form, and said plate 42 has a part 43 bent over the top of the ,and threaded into said car.

It will be seen that end of said lever is adapted to bar 2 as before. Thelower edge of said v late 42 is bent under the lower edge ofthej har 2. and two; ,binding: screws are? threaded through'the' flange thus formed and tightened to hold the plate in place. An ear 45 is formed and bent. olf from the plate 42 so as to have a flat horizontal to and .the main key lever 46 is pivoted to saiear 45 on a screw 47 having a vertical axis The forward end of -"this lever is bent up to form a handle or key 48 adapted to -be swung toward the right by the edge of the body portion of the operators hand. 'Itjwill be seen that this ca'n be donewithout removing the fingers from over the printingkeys"49,-

Thef lever-.46 has an ear or lever arm 50. that lies in front of a vertical sub-lever 51 of the third order, which is pivoted at 52" to the plate 42 and which at its upper. endstands in front of the button-or key 24.. The

.construction is such that when the key lever v 46 is thrown toward the right the ear or lever arm 50 moves toward the rearof the machine and operates the tabulator throughthe lever 51 and the key 24. The return motion of the parts of. the attachment is limited by a stop which is here shown as consisting of i a lug '52bent up from the ear 45 in posi tion to arrest an arm or lug 53 on the lever 46' when the parts reach normal position.

It has been found in practice that a de-' vice of this character expedites considerably the execution 'of work involving the frequent use of the tabulator. For example, some railroad billing work requires wide sheetslof' paper and on said sheets short: items are written in a number of columns. In doing this work the tabulator is in .constant demand. With a device onthe machine of the character described, the operator can write an item and then with the palm of the hand depress the key 32 or with the edge of the hand strike aside the key 48 without moving the fingers from the printing keyboard. Even while holdin the auxiliary tabulator key in its operate position the fingers of the right. hand are poised over the printing keys ready for action the instant the carriage is arrested by the tabulator stops. Moreover, this key is" in such position and is-operated by such a part of the hand that the operator does not have to look at it or to fix his attention on it in order to operate it successfully. The operators mind is thus .not diverted from the matter to be writtern This auxiliary actuating mechanism can be built into the m him if desired but prefer to make it as an attachment as shown which can be added to existing machines at slight expense and with little trouble. It

will also be observed that the auxiliary actuatin mechanism is loosely connected to the tabulator mechanism, proper and comneed-e40 prises two levers connected together, the

main -lever bearing the large key to be operated by thepalm or hand of the operator, and the other or supplemental lever to more immediately act on the tabulator mechanism proper, said supplemental lever being so connected to said main lever as to cause the supplemental or sub-lever .to act in the proper direction to be effective on the tabulator mechanism. The auxiliary actuating mechanism itwill also be noted comprises a system of levers, at least two in number, for transmitting the blow of the hand in proper direction and causing the final lever to work to the required extent to operate on the tabulator.

The invention is, of course, adapted or adaptable foruse in connection with other styles oft-ypewriting machines, having other sorts of tabulator keys; and it is obviously not essential that the attachment operate directly on the finger key itself.
